vided'at one end 'ofthe pin 16 for locking the i i This invention relates to insulator supports and more particularly to'hooks for connecting the insulator to a supporting rack.

An' object of this invention is to provide '5 an insulator hook for mounting insulators on a rack that shall be simple 1n structure and inexpensive to manufacture.

Another object of this invention is to provide an insulator hook for engaging arack that shall be especially adaptable or over head mountings.

A further object of this invention is to provide a hook having the above characteristics and means that shall rigidly lock the hook to a rack.

These and other objects that may be made apparent throughout the further description of this invention are attained by means of the apparatus hereinafter described and illustrated in the accompanying drawings wherein, I

Figure 1 is a perspective view of an insulator rack having disposed thereon two insulator hooks, each of which illustrate a slightly different embodiment of the invention.

Fig. 2 is a perspective view of one form of an insulator hook embodying the invention. A.

80 Fig. 3 is a sectional view taken along the line 3-3 of Fig. 1. p

In the drawings, 11 is an insulator rack having an opening 12 disposed in each of its ends for cooperating with any su table means (not shown) for fastening the rack to a wall or roof as maybe desired. The insulator rack is provided with spaced openings 13 of T-shape. The insulator rac'kmay be of any desired length and provided w1th apart at any predetermined distance One form of a hook embodying this invention is illustrated at 14 in Fig. 1. Fig. 2 is a perspective view of this same form of a fastening the hook 14 to the rack 11. p

The hook 14 comprises a pin 16 for receiving an insulator or insulators 17 and'is provided with a washer 19 for retaining-the insulator on the pin 16. a A cotter pin 21 is proany number of T-shaped' openings spaced Referring particularly to Flg. 3 which is a hook showing more in detail a means 15 for washerl9 and insulators 17 on the pin-16. The pin116 is disposed on a U-shaped base member 22 and the arms 23 and 24 of the U- shaped base member terminate in the form-of a T- for engaging and cooperating with the openings-13 isposed in the rack 11.

The dimensions of the T-shapedarms 23 and 24 are substantially the same as the inner dimensions of the T-shaped openin s 13. It

can be seen from the drawings that t e means 15 for connecting thehook to the rack c'omprises the T-shap'ed arms 23 and- -24whicl are adapted to be received by the head por-' tion of the T-shaped openings 13, the'distance between the T-sha ed. arms being sub: stantially the same as the: distance between adjacent openings 13. The slots- 25. formed *bythe T.-shape of the arms 23-and 24phave substantially the same dimensions as the corresponding portions 26 adjacent the openings 13 and areadapted to receive the portions26.

The form of a hook illustrated at 14 is very simple, inexpensive to manufacture and is easily attached and detached from the rack. This form of hook-is very de'sirablefor use with racks mounted perpendicularly.

- Another form of hook illustrating a slightly difierent embodimentofthis invention is shown at 31- in.F-ig. -1. The base member 22 and'arms 23' and 24. are substantially the same as'that described-for the book 14 and the baselmember 22 of "the hook 31'is provided witha bolt'32 having a head ortion 33 on one .of'q-its: ends, the other on bein connected to the base member 22 by a threa .ed means 34. j The threadedmeans 34 is pro- 1 vided with a locking nut 35 forlocking the bolt 32 infixed relation tothebase 22.

sectional view taken. along the line 33 of Fig.1, the bolt 321 is employed to lockthe 32 into the basemember 22 unti1. the point of-the bolt comes in contact'with the rack 11 which-tightly fastens the baseflmember. tov the 'rackll. The locking nut 35 serves to lock the rack.

the point of the bolt locks the base member 22. to the rack in rigid fixed relation. Iihe boltt32ior P ay b any desired le'I if-lth 1 avenues said rack, aninsulator supporting pin threaded through said member and adapted to engage said rack for locking said member in place, and means for locking said pin against movement.

for supporting any required number of insulators. t 7

While I have illustrated and-described'this invention in connection with'mountings of,

round or spool insulators it will be obvious to those skilled in the art that themeans 15 may'readily be adapted for fastening'any type of'insulator havinga suitable support to the basemember 22 and that the hooks described above may be positioned to mount inw sulators forsupporting'both horizontal and vertical cables. It will alsobe obvious. that 'a 'singlerhook'may be adapted for mounting one'or. more insulators. and. likewise one or more. hooks -may be employedfor -,mount1'ng insulatorsfor supporting asingle cable therebetween. Gther changes, modifications, substitution's,.= additions and omissions may' be made Withoutdepartingfrom thespirit and scone-of the-appendedclaims.
